Definition: Given a passage with a context and an answer, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.
Input: Context: To ascertain whether inoculation of lipopolysaccharide (LPS) into the mouse cochlea might induce enhancement of DNA binding activity of NK-kappa B and to establish a positive model of NF-kappa B activation in the cochlea.', 'Two groups of CBA mice were transtympanically injected either with 10 micrograms of LPS or an equal volume of saline. The nuclear proteins of the cochlea were extracted, quantitated and bound with 32P-radiolabeled oligonucleotide probe for NF-kappa B. The bound and free probes were separated by electrophoresis on a 4.5% native polyacrylamide gel. Supershift assays were carried out using the antibodies against NF-kappa B subunit P65 and P50.', 'The radiolabeled probe bound differently to nuclear extracts from the LPS-treated and the saline-treated mouse cochleae, showing that LPS inoculation significantly increased NF-kappa B binding activity. Supershift analysis demonstrated that the enhancement of DNA binding activity was related to both P65 and P50 subunits.
Answer: LPS could induce NF-kappa B activation in the cochlea. Moreover, this study implies that tissues from LPS-inoculated cochlea might serve as a useful positive control in the study on activation of NF-kappa B in cochlea.
